The transpyloric plane is a key horizontal reference line on the anterior abdominal wall. Which of the following structures lies on this plane?

• A Pylorus of the stomach ✓
• B Base of the appendix
• C Umbilicus
• D Hilum of the spleen

Explanation

The transpyloric plane passes midway between the suprasternal notch and the pubic symphysis, roughly halfway between the xiphisternum and the umbilicus, and lies at the L1 vertebral level. It passes through the pylorus, the duodenojejunal flexure, the neck of the pancreas, the hila of both kidneys, and the origin of the superior mesenteric artery. The base of the appendix lies near McBurney's point well below this plane, and the umbilicus lies at the L3 to L4 disc level.
